Thus the mechanism is adapted to operate practically instantaneously between piles Without any strains or vibration or abrupt starting or stopping movements.

The invention thus briefly outlined may be embodied in various concrete structures, and the preferred structures are illustrated in the accompanying drawings.

Referring lirst to Figures 1 and 2, the invention is illustrated as used at the delivery end of a printing` machine in which a collected folded product is being produced, though it will, of course, be understood, and as will hereinafter appear, the invention is not to be restricted to this particular use. As shown in these lfigures, the various parts of the mechanism are supported in suit-able frame work consisting of vertical standards a and cross bars Z of any usual or desirable configurations. The particular mechanism shoivn in these figures includes a folding and collecting cylinder 1, this cylinder being provided with usual sheet taking devices as grip- )ers 3 and folding blades el. These folding lades fold od into folding ja-ivs 5, on what may be termed a delivery cylinder These cylinders 1 2 are or may be supported in any usual or suitable manner, as on shafts 1, -2 suitably supported in the frames Z), before referred to.V These cylinders may, if desired, have associated therewith guides 5, 7, S, 9, for folding cylinder 1 and a guide 11 for the delivery cylinder 2, these guides acting to accurately pass the products through the mechanism. The products are forwarded to the guides 6 7 from any usual printing mechanism, not illustrated.

Associated with the delivery cylinder 2 are or may be provided stripper lingers 12, these fingers acting to guide the product from the delivery cylinder to the collector hereinafter referred to.

rl`he collector or receiver which forms one of the important features of the present invention may be of various configurations, bu t Will be stationarily mounted with respect to the mechanism with which it is associated and Will include a plurality of pockets or compartments. The collector chosen to illustrate the invention comprises a fan shaped structure provded with a plurality of blades or arms 13, which are in the construction shown set at right angles, thus forming four adjacent pockets or compartment into which the products may be d epositcd from the delivery cylinder 2. VIt will., of course, be understood that the form, arrangement, and number of these pockets may be varied as desired, depending on the particular cial-*sof work for Which the machine is designed or used.

These bladesare mounted on a shaft 1-4- suitably supported in bearings` "11 in the frame of tl e machine and are, sce 1figure Q,

provided With recesses 15 to permit them to pass the stripper fingers 12, before referred to, and With other Wider recesses 16 to permit the passage of mechanisms hereinafter referred to.

rllie receivers in the particular construction illustrated are formed to receive a bunch or pile of a predetermined number of products which are to form the pile required, such a number being received or collected in one of the pockets. After this number has been collected the receiver is given a rotary movement, a. quarter turn the present instance,v

and the succeeding pocket brought into receiving position, the collected pile being deposited on a carrier, hereinabove referred to. lVhile this collector actuating mechanism may be of various characters, in the particular constructon illustrated it is actuated through a paivl and ratcht mechanism driven in any suitable Way.Y in the particular construction shown the shaft 111, outside the side frames, has secured thereto a hub 18, having fast thereon a ratchet 19. This ratchet in the particular construction illustrated has a series of deep teeth 20, the number of these teeth being equal to the number of the fan blades, so thatas the ratchet is moved the length of a deep tooth the collector is give-` he required rotary advancing n'iovement. Adjacentthe ratchet 19 s a second ratchet 21, this ratchet being provided with a number of teeth, depending on the number of products it is desired to collect in a pile. rihis second ratchet Q1 is loose on the hub and is provided With one or more deep 'teeth 21, one such tooth being' shoivn. These ratchets are operated by means of a lever 22, pivotad loosely on the shaft 14;, before referred to. @ne arm of this lever has secured thereto an operating paivl 23, which cooperates With the ratchets 19, 21 to advance the same, this advancing movement taking place when Ythe deep teeth 20, in theratchcts 19, Q1 register; to the other arm of the lever there secured one end of an operating rod Q-l, the other end of this rod being secured to a stud 25, on a gear QG, mounted on stud 2'7 supported in one of the standards a of the chine frame., this gear 26 being driven from -the collecting cylinder driving gear 260.

ln the best constructions means are provided to prevent backward moven'ient of the ratchetsor any undesired movement in the r tcliets ortheir associated parts. ln the particular construction illustrated this is: effected by means of a locking paivl Q8, carried on a stud Q9 securedv in the machine frame, this stud being spring pressed to l-:eep the paivl 28 in operative relation with the ratcl'iet 21, b v means of coiled spring 30mterposed between the ratchet and the machine frame. 1f desired to strengthen the parts and assist in 'supporting the ratchet mechanism and its associated parts, a bracket 31 lllU may ,be secured the machine frame, the depending le of this bracketfor'iningadditionJ ta'l bearing joi"tlieshaft 14-beyond the'ratcliet mechanism'.

Cooperating Wit Y" the'4 receiver or collector is al carrier', this` carrierwhaving atraveling I'novemen't to receive and advance .successi-ve piles orA stacks of products deposited thereon by the collector. This carrier may be ofva-A rious Constr ctions and operated in various vvays. It will, lioivevei', b`e operated so as to haver]` continuousmotion, and this motion willbe' at a comparatively slow speed, so that abrupt starting' orf stopping-movements are avoided and there ifs ve'ry little Wear and tear on the parts.v rlhis movement niay be given the carrier in any suitable manner. In the particular machine illustrated'thismoveinent is effected from the delivery cylinder, the partS being` tinied soth'a't` the Ycarrier has moved slightly more than the Width of a pile bythe time anotherpileY is ready for deposit thereon from the"l collector. As shown, the shaft 2 of the delivery cylinder 2 has secured thereto a- Worm 32 which engages with' a ivorin33A on the end of aflsliort vertical shaft 34, this shaft running in bearings 'S5- '36, mountedin -brackets 35", 36 secured to the frame of the machine. Theshaft 34 carries on its lower end aihitregear 37, which meshes Wit-h a mitreB-S on cross shaft 39 suitably7 mounted inthe machine frame'. `This shaft 39is the drivingshaft for'thetraveling cai"- rier,l and imparts to the carrier' a steady ino tionat thedesiiedspeed. y

The specific constructionof the carrier may `be. variedvvithin vv'i le limits, and tivo forms of carrier are illustrated in the-drawings.

`Referriig first to rFic-ares; i and athecarrier is shown as coinpivisinga series of endless belts 17, Whichare given amcontinuouspadvancing movement' through the folding mechanism. '0n the shaft 39, before referred to, is a series `of pulleys 40, one `suchv pulley being provided; for each of thebelts likewise, fixedly'secuied on `this shaft is a 'sprocket Wheel 41, which drives a sprocket chain 42. This `sprocket chain imparts "movement to supporting arid` driving; rolls 431, 44 and 45, supported on shafts 430,440 and 450 by means ofsprockets 4,3', 44 'and 45- secured on' one end of the shafts. As before stated, the fan blades 13 are providedvivith the 'wide recesses i 16 to permit the passage ofthe'belts on the rotation of the fan, The speed of the carrier maybe as desired; fit will, however, be such in relation to the vspeed of the delivery cylinder that aseach pile'or stack of products' is depositedon 'the carrier by' theV fan such pile Will be advancedso as to clearthe fan and provide a'space `ferth'e nest succeeding `pile of products;

A guard v46, suitably secured jon the frame i Work of theniachiiie, niay be provided if desired for preventing displacement of the prodposition by a iock 'nut 5G.`

ucts as they are depositedin the pockets of the fan'.

Referring` now to Figures 3? and 4, a soins- What modifield' forinof carrieris shown'. ln the construction here shown the pile receiving surface of the` carrieris intheforni of pockets', this construction beingadapted for usewvith special types of products, such,ifor insta-nce, as uncollected or unfolded sheets, which class ofV products are difficult to pile evenly on plain fiat belts. In the particular construction illustratedv these pockets are formed by a series off fingers 48, which' are carried on a pair of sprocket chains 47, these sprocket chains being spaced so as to form pockets of the required width. iVliile' these chains may be mounted and driven in any desired/nianner,` they are, as shown, arranged to extend from a point in advance of the arc described by the fan blades so Vthat they do not interfere with the fan and to lie on each side of a pair of the belts 17 before referred to. In the particular constri'iction illustrated the roll shaft 430, before referred to, provided With a pair of fixed sprockets 4t) Figure 5),- the shaft 440 with loose .sprockets 49', and the shaft V450 with sprockets 50, the chains 47 thus beingdriven to ac Vance the chains a pocket length at the required time. Vit-li this construction the pile. of products is deposited by the fan on the belt 17 as in the construction shown in Figures 1 and 2, the pile being advanced by the bcits for a short advancing increment. However, a pocket finger is brought into position to engage the rear end of the pile andthe pile is forwarded under control of the pocket fingers to effect the deposit of an even pile of products. is the products are deposited by the fan blades they bring up against stop" fingers 57, suitably supported on a shaft 58, suitably secured in the frame, the function of these fingers being to keep the pile in alignment. These fingers pro]ect through the fan blade in the spaces 15, before referred to, so as not to interfer with the rotation of the fan blades In the best constructions means are provided for tightening' the sprocket chains 47.

VVhile this nia be effected in various iva s as shown, theV shaft 430 of the roll 43 is mounted in sliding bearings 51, which move in runways 52 formed in the side frames of the machine. One of these bearings 51 is provided with a projection or abutment 55, against which bears one end of an adjusting screw 54, threaded through a thrust block 53N this adjustinof bolt being' looked in adjusted The chains 42 and belt 17 may be ti Q'htened 'by means of a chain adjusting' sprocket 500 anda belt adjustingroll 501, as is used in these chain carriers.

ln Figure 61s illustrated `the improved delivery used in connection with a machine for deliverino cards and the like, in which the product is separated Yfrom a web and delivered to a fan, practically continuously without collecting or folding. As here shown diagrammatically, a web IV is fed through a pair ot slitting rolls 505, 500, this slit web being directed under a reciprocating knife 507 which cuts ofi' the products and delivers them to the collector or receiver. In this niodilication the collect-or and carrier will be constructed and operated as above described in connection with Figures 1 5.

The operation ot' the mechanism described may be briefly summarized as follows: The carrier belts are driven with a slow cont-inuous movement at a speed depending on the products it is desired to associate in a pile. The products are delivered to .the collector, and through the pawl and ratchet mechanism 19, 2l the desired number ot' products are delivered to a pocket ot'. the collector. At'ter this has been done, the collector is given a quarter turn and, as the blades ot the collector pass between the belts, the associated products are laid or deposited on the belts in an even pile. This rotary movement oiI the collector may be very quickly etl'ected, and by this movement a succeedingl holder or pocket of the collector is brought into product receiving position for assembling a second pile ot' products, and the carrier has moved forward a sufficient distance to provide space for another pile of products.

lVith the construction shown and described a very ellicient pile delivery7 has been provided, in which the products are delivered,

accurately counted in piles, and in which time lost, due to stoppage ot the mechanism tor CTI repairs or adjustment, is reduced to a minimum.
